CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is based on and claims priority under 35 U.S.C. § 119(a) of a Korean patent application number 10-2018-0122922, filed on Oct. 16, 2018, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.

BACKGROUND 1. Field

The disclosure relates to an antenna using a single non-conductive portion and an electronic device including the antenna.

2. Description of the Related Art

Advances in electronics and communication technologies have enabled development of electronic devices having various functions and shapes. Such electronic devices are convergence devices that can perform one or more functions in combination.

As the functional gap between manufacturers has narrowed significantly in recent years, to satisfy consumer needs, electronic devices are becoming slimmer, while conductive members (e.g., metal frames or metal bezels) are used to increase their rigidity. In the case of an electronic device for communication, at least a portion of the conductive member may be used as the antenna for slimming, which requires improvement in radiation performance.

When the exterior of an electronic device is made of a conductive member (e.g., metal frame or metal bezel) to meet the slimming trend of electronic devices, unlike an injection molded dielectric material, the antenna is not separately designed but at least a portion of the conductive member may be used as the antenna. For example, when a conductive member serving as the side member of the electronic device is used as an antenna, the segment between conductive members may be filled with a non-conductive dielectric material and may be used as an insulation part for electrically disconnecting a specific location of the conductive member. Hence, the electrical length of the antenna from the feeder can be adjusted, enabling the antenna to operate in a specified frequency band.

The antenna may be utilized as a radiator by feeding a unit conductive portion of the conductive member electrically insulated by a pair of non-conductive portions spaced at a given interval. For example, it is preferable to design the antenna so as to cover various low bands required by the operator. However, the unit conductive portion segmented by the pair of non-conductive portions has a limited physical length due to the slimming of the electronic device, and cannot cover various low bands even when a matching circuit or an additional radiator is used. In addition, even when the frequency is shifted in the low band by using a matching circuit or an additional radiator, the performance may be degraded as the frequency shifts to a lower frequency owing to the limitation of the physical length of the conductive portion.

The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

For example, the recess 201 may have a first width (W1) between a first portion 220 a of the second housing structure 220 parallel to the folding axis (A axis) and a first portion 210 a of the first housing structure 210 formed at the edge of the sensor region 231 d, and have a second width (W2) between a second portion 220 b of the second housing structure 220 and a second portion 210 b of the first housing structure 210 that does not correspond to the sensor region 213 d and is parallel to the folding axis (A axis).

The second width (W2) may be wider than the first width (W1). The recess 201 may be formed to have the first width (W1) ranging from the first portion 210 a of the first housing structure 210 to the first portion 220 a of the second housing structure 220 (asymmetric shape), and the second width (W2) ranging from the second portion 210 b of the first housing structure 210 to the second portion 220 b of the second housing structure 220 (symmetric shape). In one embodiment, the first portion 210 a and the second portion 210 b of the first housing structure 210 may be located at different distances from the folding axis (A axis). The width of the recess 201 is not limited to the example shown above. In various embodiments, the recess 201 may have two or more different widths owing to the shape of the sensor region 213 d or the asymmetry of the first housing structure 210 or the second housing structure 220.

In one embodiment, at least a portion of the first housing structure 210 and the second housing structure 220 may be made of a metal or non-metal material having a rigidity value selected to support the display 230.

In one embodiment, the sensor region 231 d may be formed to have a preset area near to one corner of the first housing structure 210. However, the arrangement, shape, or size of the sensor region 231 d is not limited to the illustrated example. For example, in a certain embodiment, the sensor region 231 d may be formed at another corner of the first housing structure 210 or in any region between the upper corner and the lower corner. In another embodiment, the sensor region 231 d may be disposed at a portion of the second housing structure 220. In another embodiment, the sensor region 231 d may be formed to extend between the first housing structure 210 and the second housing structure 220. In one embodiment, to perform various functions, the electronic device 200 may include components exposed to the front surface of the electronic device 200 through the sensor region 213 d or through one or more openings provided in the sensor region 231 d. The components may include, for example, at least one of a front camera, a receiver, a proximity sensor, an illuminance sensor, an iris recognition sensor, an ultrasonic sensor, or an indicator.

In one embodiment, the first rear cover 240 may be disposed on the second surface 212 of the first housing structure 210 and may have a substantially rectangular periphery. In one embodiment, at least a portion of the periphery may be wrapped by the first housing structure 210. Similarly, the second rear cover 250 may be disposed on the fourth surface 222 of the second housing structure 220, and at least a portion of the periphery thereof may be wrapped by the second housing structure 220.

In the illustrated embodiment, the first rear cover 240 and the second rear cover 250 may have a substantially symmetrical shape with respect to the folding axis (A axis). In another embodiment, the first rear cover 240 and the second rear cover 250 may have various different shapes. In another embodiment, the first rear cover 240 may be formed as a single body with the first housing structure 210, and the second rear cover 250 may be formed as a single body with the second housing structure 220.

In one embodiment, the first rear cover 240, the second rear cover 250, the first housing structure 210, and the second housing structure 220 may be combined with each other so as to provide a space where various components (e.g., printed circuit board, antenna module, sensor module, and battery) of the electronic device 200 can be arranged. In one embodiment, one or more components may be disposed on or visually exposed via the rear surface of the electronic device 200. For example, one or more components or sensors may be visually exposed through the first rear region 241 of the first rear cover 240. The sensors may include a proximity sensor, a rear camera, and/or a flash. In another embodiment, at least a portion of the sub-display 252 may be visually exposed through the second rear region 251 of the second rear cover 250.

The display 200 may be disposed on the space formed by the pair of housing structures 210 and 220. For example, the display 200 may be seated in the recess (e.g., recess 201 in FIG. 2A) formed by the pair of housing structures 210 and 220, and may be disposed to substantially occupy most of the front surface of the electronic device 200. The front surface of the electronic device 200 may include the display 230, a portion (e.g., edge region) of the first housing structure 210 close to the display 230, and a portion (e.g. edge region) of the second housing structure 220 close to the display 230. In one embodiment, the rear surface of the electronic device 200 may include the first rear cover 240, a portion (e.g., edge region) of the first housing structure 210 close to the first rear cover 240, the second rear cover 250, and a portion (e.g. edge region) of the second housing structure 220 close to the second rear cover 250.

In one embodiment, the display 230 may refer to a display who's at least a portion may be deformed into a flat or curved surface. In one embodiment, the display 230 may include a folding region 231 c, a first region 231 a disposed on one side (e.g., right side of the folding region 231 c) with respect to the folding region 231 c, and a second region 231 b disposed on the other side (e.g., left side of the folding region 231 c). For example, the first region 231 a may be disposed on the first surface 211 of the first housing structure 210, and the second region 231 b may be disposed on the third surface 221 of the second housing structure 220. This demarcation of the display 230 is only an example, and the display 230 may be subdivided into plural regions (e.g., four or more regions) according to the structure or functionality. For example, in the embodiment of FIG. 2A, the area of the display 230 may be subdivided with respect to the folding area 231 c or the folding axis (A axis) extending parallel to the y-axis. However, in another embodiment, the area of the display 230 may be subdivided with respect to a different folding region (e.g., folding region parallel to the x-axis) or a different folding axis (e.g., folding axis parallel to the x-axis). The aforementioned subdivision of the display is only a physical demarcation based on the pair of housing structures 210 and 220 and the hinge structure (e.g., hinge structure 264 in FIG. 3), and the display 230 may substantially present one full screen through the pair of housing structures 210 and 220 and the hinge structure (e.g., hinge structure 264 in FIG. 3). In one embodiment, the first region 231 a and the second region 231 b may have a symmetrical shape with respect to the folding region 231 c. Although the first region 231 a may include a notch region (e.g., notch region 233 in FIG. 3) cut according to the presence of the sensor region 231 d, it may have a symmetrical shape with the second region 231 b in other portions. In other words, the first region 231 a and the second region 231 b may include portions with symmetrical shapes and portions with asymmetrical shapes.

Referring to FIG. 2B, the hinge cover 265 may be disposed between the first housing structure 210 and the second housing structure 220 so as to cover the internal components (e.g., hinge structure 264 in FIG. 3). In one embodiment, the hinge cover 265 may be covered by portions of the first housing structure 210 and the second housing structure 220 or be exposed to the outside according to the operating state (e.g., flat state or folded state) of the electronic device 200.

For example, when the electronic device 200 is in the flat state as shown in FIG. 2A, the hinge cover 265 may be covered by the first housing structure 210 and the second housing structure 220 so as not to be exposed. When the electronic device 200 is in the folded state (e.g., completely folded state) as shown in FIG. 2B, the hinge cover 265 may be exposed to the outside between the first housing structure 210 and the second housing structure 220. When the electronic device 200 is in the intermediate state where the first housing structure 210 and the second housing structure 220 make a certain angle, the hinge cover 265 may be partially exposed to the outside between the first housing structure 210 and the second housing structure 220. In this case, the exposed portion may be less than that for the fully folded state. In one embodiment, the hinge cover 265 may include a curved surface.

Next, a description is given of configurations of the first housing structure 210 and the second housing structure 220 and regions of the display 230 according to the operating state (e.g. flat state or folded state) of the electronic device 200.

In one embodiment, when the electronic device 200 is in the flat state (e.g., state of FIG. 2A), the first housing structure 210 and the second housing structure 220 may make an angle of 180 degrees, and the first region 231 a and the second region 231 b of the display may be disposed to face in the same direction. In addition, the folding region 231 c may be coplanar with the first region 231 a and the second region 231 b.

In one embodiment, when the electronic device 200 is in the folded state (e.g., state of FIG. 2B), the first housing structure 210 and the second housing structure 220 may be disposed to face each other. The first region 231 a and the second region 231 b of the display 230 may face each other, making a narrow angle (e.g., between 0 degrees and 10 degrees). At least a portion of the folding area 231 c may form a curved surface with a preset curvature.

In one embodiment, when the electronic device 200 is in the intermediate state, the first housing structure 210 and the second housing structure 220 may be disposed to make a certain angle. The first region 231 a and the second region 231 b of the display 230 may form an angle greater than that for the folded state and less than that for the flat state. At least a portion of the folding area 231 c may form a curved surface with a preset curvature. This curvature may be less than that for the folded state.

FIG. 3 is an exploded perspective view of an electronic device according to an embodiment of the disclosure.

Referring to FIG. 3, in one embodiment, the electronic device 200 may include a display 230, a support member assembly 260, at least one printed circuit board 270, a first housing structure 210, a second housing structure 220, a first rear cover 240, and a second rear cover 250. In the description, the display 230 may be referred to as a display unit, display module, or display assembly.

The display 230 may include a display panel 231 (e.g., flexible display panel), and at least one plate 232 or layer on which the display panel 231 is seated. In one embodiment, the plate 232 may be disposed between the display panel 231 and the support member assembly 260. The display panel 231 may be disposed on at least a portion of one surface (e.g., surface in the Z direction in FIG. 3) of the plate 232. The plate 232 may be formed in a shape corresponding to the display panel 231. For example, a portion of the plate 232 may be formed in a shape corresponding to the notch region 233 of the display panel 231.

The support member assembly 260 may include a first support member 261, a second support member 262, a hinge structure 264 disposed between the first support member 261 and the second support member 262, a hinge cover 265 to cover the hinge structure 264 when viewed from the outside, and a wiring member 263 (e.g., flexible printed circuit board (FPCB)) that crosses the first support member 261 and the second support member 262.

In one embodiment, the support member assembly 260 may be disposed between the plate 232 and at least one printed circuit board 270. For example, the first support member 261 may be disposed between the first region 231 a of the display 230 and the first printed circuit board 271. The second support member 262 may be disposed between the second region 231 b of the display 230 and the second printed circuit board 272.

In one embodiment, at least a portion of the wiring member 263 and the hinge structure 264 may be disposed within the support member assembly 260. The wiring member 263 may be disposed in a direction crossing the first support member 261 and the second support member 262 (e.g., x-axis direction). The wiring member 263 may be disposed in a direction (e.g., x-axis direction) perpendicular to the folding axis (e.g., y-axis or folding axis (A) in FIG. 2) of the folding region 231 c.

The at least one printed circuit board 270 may include, as described above, the first printed circuit board 271 disposed on the side of the first support member 261, and the second printed circuit board 272 disposed on the side of the second support member 262. The first printed circuit board 271 and the second printed circuit board 272 may be disposed inside the space formed by the support member assembly 260, the first housing structure 210, the second housing structure 220, the first rear cover 240, and the second rear cover 250. Various components for implementing functions of the electronic device 200 may be mounted on the first printed circuit board 271 and the second printed circuit board 272.

In one embodiment, in a state where the display 230 is coupled to the support member assembly 260, the first housing structure 210 and the second housing structure 220 may be assembled to each other so as to be coupled to both sides of the support member assembly 260. As described below, the first housing structure 210 and the second housing structure 220 may be coupled to the support member assembly 260 by being slid on both sides of the support member assembly 260.

In one embodiment, the first housing structure 210 may include a first rotary support surface 214, and the second housing structure 520 may include a second rotary support surface 224 corresponding to the first rotary support surface 214. The first rotary support surface 214 and the second rotary support surface 224 may include a curved surface corresponding to the curved surface included in the hinge cover 265.

In one embodiment, when the electronic device 200 is in the flat state (e.g., state of FIG. 2A), the first rotary support surface 214 and the second rotary support surface 224 may cover the hinge cover 265 so that the hinge cover 265 may be not or minimally exposed to the rear surface of the electronic device 200. When the electronic device 200 is in the folded state (e.g., state of FIG. 2B), the first rotary support surface 214 and the second rotary support surface 224 may rotate along the curved surface included in the hinge cover 265 so that the hinge cover 265 may be maximally exposed to the rear surface of the electronic device 200.

The antenna according to various embodiments of the disclosure may be applied to the first housing structure, and may be configured to shift in a relatively wide range of a low band without degrading radiation performance. Next, a description is given of the antenna.

FIG. 4A and 4B are a view of an electronic device illustrating the arrangement of conductive portions segmented by a single non-conductive portion according to various embodiments of the disclosure.

Embodiments for the electronic device 400 of FIGS. 4A and 4B may be at least partially similar to or different from those for the electronic device 200 of FIGS. 2A to 3.

Referring to FIG. 4A, the electronic device 400 may include foldable housing structures 410 and 420 rotatably arranged with respect to the folding axis A. In one embodiment, the foldable housing structures may include a first housing structure 410 and a second housing structure 420. In one embodiment, the first housing structure 410 and the second housing structure 420 may be rotatably coupled via the hinge structure 460 (e.g., hinge structure 264 in FIG. 3) having a hinge cover 465. For example, through the hinge structure 460, the first housing structure 410 and the second housing structure 420 may be folded to face each other with respect to the folding axis A, or may be unfolded to be coplanar.

In various embodiments, the first housing structure 410 may include a first surface 411 facing in a first direction (e.g., Z-axis direction in FIG. 3), a second surface 412 facing in a second direction opposite to the first direction (e.g., negative Z-axis direction in FIG. 3), and a first side member 413 enclosing at least a portion of the space between the first surface 411 and the second surface 412. In one embodiment, at least a portion of the first side member 413 may be made of a conductive member (e.g., metal member). In one embodiment, at least a portion of the conductive member of the first side member 413 may be applied as an antenna (A1). In one embodiment, the first side member 413 may include a first conductive portion 4131, a first non-conductive portion 4132, and a second conductive portion 4133 arranged in sequence from the hinge structure 460.

In various embodiments, the second housing structure 420 may include a third surface 421 facing in a third direction (e.g., Z-axis direction in FIG. 3), a fourth surface 422 facing in a fourth direction opposite to the third direction (e.g., negative Z-axis direction in FIG. 3), and a second side member 423 enclosing at least a portion of the space between the third surface 421 and the fourth surface 422. In one embodiment, at least a portion of the second side member 423 may be made of a conductive member. In one embodiment, the second side member 423 may include a third conductive portion 4231, a second non-conductive portion 4232, a fourth conductive portion 4233, a third non-conductive portion 4234, and/or a fifth conductive portion 4235 arranged in sequence from the hinge structure 460.

In various embodiments, when the first housing structure 410 and the second housing structure 420 are unfolded with 180 degrees, the first surface 411 and the third surface 421 may be formed to be of a planar shape facing the same direction (e.g., Z-axis direction in FIG. 3). In one embodiment, the electronic device 400 may include a display 430 disposed to cross the first surface 411 of the first housing structure 410 and the third surface 421 of the second housing structure 420. For example, when the first housing structure 410 and the second housing structure 420 are folded with respect to the folding axis A so that the first surface 411 and the third surface 421 face each other, the display 430 may also be folded with respect to the folding axis A. In one embodiment, the display 430 may be not disposed on at least a portion of the first surface 411 of the first housing structure 410 and a separate sensor region 435 may be disposed thereon. In another embodiment, the sensor region 435 may be disposed on at least a portion of the third surface 421 of the second housing structure 420 or may be disposed on a portion extending to the first surface 411 and the third surface 421.

In various embodiments, the electronic device 400 may be provided with an antenna Al formed using a portion (e.g., lower portion) of the first side member 413 of the first housing structure 410. In one embodiment, the antenna A1 may be formed through the second conductive portion 4133 segmented by the first non-conductive portion 4132 of the first side member 413. In this case, the second conductive portion 4133 may be formed to have an electrical length relatively longer than that of the antenna formed as the unit conductive portion by a pair of non-conductive portions. In another embodiment, the antenna A1 may be disposed in an upper region of the first housing structure 410 or in a side region connecting the upper region and the lower region thereof.

In various embodiments of the disclosure, the antenna A1 may include a pair of feeders disposed at different positions from the first non-conductive portion 4132, and may be configured to reduce the degradation of the radiation performance in the low band and to shift in a relatively wide bandwidth through selective feeding of the feeders.

In one embodiment of the disclosure, the antenna A1 may be configured to operate in a lower frequency band compared with the case of direct feeding by forming at least one of the pair of feeders through coupled feeding although the second conductive portion 4133 has the same electrical length. In one embodiment, the antenna A1 may be configured to shift the frequency in the range of 750 MHz to 1200 MHz in the low band.

Referring to FIG. 4B, when the first housing structure 410 and the second housing structure 420 of the electronic device 400 are folded to face each other, the second non-conductive portion 4232 of the second housing structure 420 may be disposed to overlap with the first non-conductive portion 4132 of the first housing structure 410 when the second surface 412 of the first housing structure 410 is viewed from the top. In one embodiment, when the electronic device 400 is folded, the fourth conductive portion 4333 of the second housing structure 420 may reduce the radiation performance of the antenna (antenna A1 in FIG. 4A) formed by the second conductive portion 4133. For example, if the fourth conductive portion 4333 has an electrical length that is the same or similar to the operating frequency band of the second conductive portion 4133, the current applied to the second conductive portion 4133 may induce an unwanted current in the fourth conductive portion 4333, and this unwanted current may cause parasitic resonance that degrades the radiation performance of the second conductive portion 4133. To prevent this problem, the fourth conductive portion 4333 of the second housing structure 420 may be segmented by the second non-conductive portion 4132 and the third non-conductive portion 4234 into a unit conductive portion (fourth conductive portion 4333), and the fourth conductive portion 4333 being a unit conductive portion may be induced to be out-band outside the operating frequency band of the second conductive portion 4133. In another embodiment, the third non-conductive portion 4234 may be disposed at various positions to prevent interference to the operating frequency band of the second conductive portion 4133.

FIG. 5 is a view of an electronic device illustrating the arrangement of the antenna according to various embodiments of the disclosure. FIGS. 6A and 6B illustrate the configuration of the variable elements T1 and T2 shown in FIG. 5 according to an embodiment of the disclosure.

FIG. 5 illustrates the configuration of the antenna Al when the second surface of the first housing structure 410 (e.g., second surface 412 in FIG. 4A) is viewed from above.

Referring to FIG. 5, the electronic device 400 may include a first housing structure 410 and a second housing structure 420 rotatably disposed with respect to each other. In one embodiment, the first housing structure 410 and the second housing structure 420 may be rotatably connected via the hinge structure 460. For example, the first housing structure 410 and the second housing structure 420 are not separated from each other due to the hinge structure 460 and may be folded to face each other or be unfolded to be coplanar.

In various embodiments, the first housing structure 410 may include a first surface 411 facing in a first direction (e.g., Z-axis direction in FIG. 3), a second surface 412 facing in a second direction opposite to the first direction (e.g., negative Z-axis direction in FIG. 3), and a first side member 413 enclosing at least a portion of the space 4001 between the first surface 411 and the second surface 412. In one embodiment, the first side member 413 may include a first conductive portion 4131, a first non-conductive portion 4132, and a second conductive portion 4133 arranged in sequence from the hinge structure 460.

In various embodiments, the first side member 413 may include a first connection piece 4134 formed at a first position L1 and/or a second connection piece 4135 formed at a second position L2 from the first non-conductive portion 4132. The second position L2 may be closer to the first non-conductive portion 4132 than the first position L1. In one embodiment, the first connection piece 4134 and the second connection piece 4135 may each be formed as a single body with the first side member 413. For example, the first connection piece 4134 and the second connection piece 4135 may be disposed to overlap with at least a portion of the printed circuit board 470 disposed in a region of the space 4001 formed by the first side member 413.

In various embodiments, the electronic device 400 may include the printed circuit board 470 disposed in the internal space 4001 of the first side member 413. In one embodiment, the printed circuit board 470 may include a first connection portion 471 (e.g., conductive pad) electrically connected to the first connection piece 4134. For example, the first connection piece 4134 may be electrically connected to the first connection portion 471 of the printed circuit board 470 as the printed circuit board 470 is mounted in the space 4001. Alternatively, the first connection piece 4134 may be electrically connected to the first connection portion 471 of the printed circuit board 470 through a separate electrical connection part (e.g., C clip or conductive contact). In one embodiment, the printed circuit board 470 may include a first electrical path 4701 (e.g., wiring line) ranging from the first connection portion 471 to a first feeder 472 (e.g., wireless communication circuit). In one embodiment, the first feeder 472 may transmit a first signal of a first frequency band at the first position L1 of the second conductive portion 4133 electrically connected through the first electrical path 4701. Here, the first frequency band may be in the range of about 900 MHz to 1200 MHz.

FIGS. 6A and 6B illustrate the configuration of the variable elements T1 and T2 shown in FIG. 5 according to various embodiments of the disclosure.

Referring to FIG. 6A, in various embodiments, a first variable element T1 may be disposed in the middle of the first electrical path 4701. In one embodiment, the first variable element T1 may include a tuner that includes a first terminal C1 electrically connected to the first electrical path 4701, a second terminal C2 electrically connected to the ground layer G of the printed circuit board 470, and a third terminal C3 electrically connected to the first position L1 of the second conductive portion 4133. In another embodiment, the first variable element T1 may include a plurality of passive elements for selective switching. In one embodiment, because the printed circuit board 470 is in direct electrical contact with the first housing structure 410 constituting the external appearance of the electronic device 400, an electric shock prevention circuit 473 may be further included in the first electrical path 4701 to prevent electric shock caused by electrostatic discharge (ESD).

In various embodiments, the printed circuit board 470 may include a second connection portion 474 electrically connected to the second connection piece 4135. In one embodiment, the second connection piece 4135 and the printed circuit board 470 may be electrically connected to the second connection portion 474 of the printed circuit board 470 via coupled feeding. As the second conductive portion 4133 is electrically connected to the printed circuit board 470 through coupled feeding, the capacitor configuration between conductors makes the electrical length of the second conductive portion 4133 longer, thereby extending the frequency shift range in the low band. In one embodiment, the printed circuit board 470 may include a second electrical path 4702 (e.g., wiring line) ranging from the second connection portion 474 to a second feeder 475 (e.g., wireless communication circuit). In one embodiment, the second feeder 475 may transmit a second signal of a second frequency band at the second position L2 of the second conductive portion 4133 electrically connected through the second electrical path 4702. Here, the second frequency band may be in the range of about 750 MHz to 850 MHz.

Referring to FIG. 6B, in various embodiments, a second variable element T2 may be disposed in the middle of the second electrical path 4702. In one embodiment, the second variable element T2 may include a switch that includes a fourth terminal C4 electrically connected to the second electrical path 4702, a fifth terminal C5 electrically connected to the ground layer G of the printed circuit board 470, and a sixth terminal C6 coupled to the second position L2 of the second conductive portion 4133. In another embodiment, the second variable element T2 may include a plurality of passive elements or tunable ICs for selective switching. In one embodiment, because the printed circuit board 470 is in direct electrical contact with the first housing structure 410 constituting the external appearance of the electronic device 400, an electric shock prevention circuit 476 may be further included in the second electrical path 4702 to prevent electric shock caused by electrostatic discharge (ESD).

In various embodiments, the printed circuit board 470 in region B may include a third electrical path (e.g., third electrical path 4703 in FIG. 7A) and/or a fourth electrical path (e.g., fourth electrical path 4704 in FIG. 7B) electrically connecting the second position L2 of the second conductive portion 4133 and the second variable element T2.

In various embodiments, the first side member 413 may include a third connection piece 4136 disposed at a third position L3. In one embodiment, the third connection piece 4136 may be formed to extend from the first side member 413 toward the space 4001. In one embodiment, the printed circuit board 470 may include a third connection portion 477 (e.g., conductive pad) electrically connected to the third connection piece 4136. For example, the third connection piece 4136 may be electrically connected to the third connection portion 477 of the printed circuit board 470 as the printed circuit board 470 is mounted in the space 4001. Alternatively, the third connection piece 4136 may be electrically connected to the third connection portion 477 of the printed circuit board 470 through a separate electrical connection part (e.g., C clip or conductive contact). In one embodiment, the printed circuit board 470 may include a fifth electrical path 4705 (e.g., wiring line) ranging from the third connection portion 477 to the ground layer G of the printed circuit board 470. In one embodiment, the printed circuit board 470 may include an electric shock prevention capacitor 478 in the middle of the fifth electrical path 4705.

In various embodiments, the antenna (e.g., antenna A1 in FIG. 4A) may be shifted in various ranges of the low band through selective feeding of the first feeder 472 and/or the second feeder 475 with the second conductive portion 4133 of the first side member 413 and through impedance matching using the first variable element T1 and/or the second variable element T2. For example, feeding through the second feeder 475 coupled with the second conductive portion 4133 enables the antenna to perform shifting in a wider frequency range of the low band with a reduction in radiation performance degradation.

In various embodiments, the processor 480 of the electronic device 400 may collect state information of the electronic device (e.g., local information, channel information, voice or data communication information, grip information, or proximity information) through at least one sensor, and determine the current mode based on the collected state information. The processor 480 may control the first variable element T1 and/or the second variable element T2 according to the determined mode to thereby change the operating frequency range of the second conductive portion 4133 in the low band. For example, through the first variable element T1 and/or the second variable element T2, the processor 480 may control the antenna radiator utilizing the second conductive portion 4133 to selectively operate at various operating frequencies of the low band (e.g., 750 MHz to 1200 MHz) without radiation performance degradation.

FIGS. 7A and 7B illustrate the electrical connection between a second connection piece and a printed circuit board according to various embodiments of the disclosure.

FIGS. 7A and 7B are cross-sectional views of a region B where the second feeder 475 and the second conductive portion 4133 are coupled fed.

Referring to FIG. 7A, the printed circuit board 470 may include a third electrical path 4703 electrically connecting the second position (e.g., second position L2 in FIG. 5) of the second conductive portion 4133 and the second variable element (e.g., second variable element T2 in FIG. 5). In one embodiment, the printed circuit board 470 may include a first substrate surface 470 a and a second substrate surface 470 b facing away from the first substrate surface 470 a. In one embodiment, the printed circuit board 470 may include a first region 4706 (e.g., ground layer) and a second region 4707 (e.g., fill-cut region). In one embodiment, the printed circuit board 470 may include, when a first conductive pad 4472 disposed on the first substrate surface 470 a in the second region 4707 and the first substrate surface 470 a are viewed from above, a second conductive pad 4471 that is formed on the second substrate surface 470 b so as to at least partially overlap with the first conductive pad 4472 (e.g., second connection portion 474 in FIG. 5). In one embodiment, the first conductive pad 4472 may be electrically connected to the second feeder 475 through the second electrical path 4702 formed in the printed circuit board 470. In one embodiment, the second conductive pad 4471 may be electrically connected to the second connection piece 4135 extending from the second conductive portion 4133 of the first side member 413 through an electrical connection member 4477. In one embodiment, the electrical connection member 4743 may be in physical contact with the second connection piece 4135 and the second conductive pad 4741.

In various embodiments, the first conductive pad 4742 and the second conductive pad 4741 spaced apart by a first interval d1 in the printed circuit board 470 may be operated as a capacitor configuration. In one embodiment, the capacitance of the capacitor configuration may be determined according to the overlapping area between the first conductive pad 4742 and the second conductive pad 4741, and thus impedance matching of the antenna may be achieved.

Referring to FIG. 7B, the capacitance may be determined by adjusting the spacing between the first conductive pad 4742 and the second conductive pad 4741. In one embodiment, the printed circuit board 470 may include a fourth electrical path 4704 electrically connecting the second position (e.g., second position L2 in FIG. 5) of the second conductive portion 4133 and the second variable element (e.g., second variable element T2 in FIG. 5). In one embodiment, the printed circuit board 470 may include a third conductive pad 4744 disposed between the first conductive pad 4742 and the second conductive pad 4741. In one embodiment, the third conductive pad 4744 may be formed as a pattern on one of the dielectric layers 470 c of the printed circuit board 470. In one embodiment, the third conductive pad 4744 may be electrically connected to the second conductive pad 4741 through at least one conductive via 4745. Hence, the second interval d2 between the third conductive pad 4744 and the first conductive pad 4742 for a capacitor configuration may be less than the first interval d1. This may be advantageous for determining the specified capacitance when the mounting space of the conductive pads 4742 and 4741 is insufficient.

FIG. 8A is a return loss (S11) chart illustrating changes in the operating band of the antenna due to adjustment of the first feeder and the second feeder according to an embodiment of the disclosure.

Referring to FIG. 8A, the following can be seen from the chart. The antenna having the configuration shown in FIG. 5 operates at a low frequency (e.g., about 750 MHz) in a low band when the second feeder (e.g., second feeder 475 in FIG. 5) is the default (graph 801). When the second feeder (e.g., second feeder 475 in FIG. 5) is the default and the first feeder (e.g., first feeder 472 in FIG. 5) is tuned through the first variable element (e.g., first variable element T1 in FIG. 5), the antenna shifts to a higher frequency (e.g., about 850 MHz) (graph 802). When the first feeder (e.g., first feeder 472 in FIG. 5) is the default, the antenna shifts to a higher frequency (e.g., about 950 MHz) (graph 803). When the first feeder (e.g., first feeder 472 in FIG. 5) is the default and the second feeder (e.g., second feeder 475 in FIG. 5) is tuned through the second variable element (e.g., second variable element T2 in FIG. 5), the antenna shifts to a higher frequency (e.g., about 1170 MHz) (graph 804). Hence, when a pair of feeders (e.g., first feeder 472 and second feeder 475 in FIG. 5) are provided at different positions of one conductive portion (e.g., second conductive portion 4133 in FIG. 5) and coupled feeding is applied to one of the feeders (e.g., second feeder 475 in FIG. 5), it can be seen that the frequency band shifts in the range of about 750 MHz to 1200 MHz in the low band.

FIG. 8B is a chart illustrating performance of the antenna for each operating band due to adjustment of the first feeder and the second feeder according to an embodiment of the disclosure.

Referring to FIG. 8B, for the antenna having the configuration shown in FIG. 5, graph 805 indicates a case where the second feeder (e.g., second feeder 475 in FIG. 5) is the default. Graph 806 indicates a case where the second feeder (e.g., second feeder 475 in FIG. 5) is the default and the first feeder (e.g., first feeder 472 in FIG. 5) is tuned through the first variable element (e.g., first variable element T1 in FIG. 5). Graph 807 indicates a case where the first feeder (e.g., first feeder 472 in FIG. 5) is the default. It can be seen that even if the frequency shifts in the direction toward higher frequencies, the efficiency (radiation performance) is not lowered as indicated by the circular dotted line.
